To au whom t may concern:

Be it known that' l,V1cT on l/icLArN7 citizen olthe United-States,residing at East lvoline,'in the county ofltock lsland and State ofIllinois, have invented certain new and useful Improvements in rloolsfor Contracting Detachable 'I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in tools for contracting detachableautomobile rims, thus allowing the tires thereon to be readily removed.

lt is a well known fact that a great number of detachable rims used onautomobiles, are of the split ring type, and that it is necessary tomove one end of the ring inwardly, thus contracting the entire rim andallowing the tire to be removed.

Since it is practically impossible to so contract the rim by hand, it isthe object of my invention to provide a very sinple tool foraccomplishing this result.

lil/:ith this object in view, the invention re sides in certain novelfeatures of construction and combination hereinafter described andclaimed. D

In describingthe invention7 l shall refer to the accompanying drawing,wherein:

Figure il is a side elevation of a tool constructed in accordance. withmy invention, showing,y its application to use; Fig. 2 is a perspectiveview of the tool, and Fig'. 3 is a horizontal section as seen along' theplane indicated by the line 3-3 of l.

ln this drawing, constituting a part of my invention7 lt designates thedetinzbable rim of an automobile wheel., this rim being shown of thecommon split ring type. Surrounding the rim R, and removable therewith,is the usual tire T which must often be removed from the rim after thelatter has been detached from the wheel. lnerder to so remove the tire,it is necessary to contract the rim by moving one of its ends inwardlyto the extent shown in Fig. l, or to a greater extent. For accomplishingthis result, a tool constituting the gist of the present invention isprovided.

' The aforesaid tool is here shown as coiny prising a plui'fality'of`links, two of which,

designated by the numerals l `and 2, are disposed in substantialalineinent. The

lVheel-Rims and outer ends of these links are provided with hooks 3adapted to engage the rim, shown in Figs. l and 3, while the inner endol the link 2 is ulcrunied, by the provision ot a bolt Ll, to the corneroi 'an angular lever 5, the resistance arm of this lever being;` pivotally connected by a bolt G with the inner and of the link l. The.lattelis preferably provided with a plurality of openings 7, any one ofwhich may receive the bolt G, thereby allowing the distance between thetwo hooks 3 to be varied.

As most clearly disclosed in Figs. l and 2. the power arm of the angularlever 5 lies substantially parallel to the link l when the tool is inoperation upon the rim, in w rich position it may be retained byinserting it through any one olf the links of a chain 8, which isconnected to the link l near its outer end.

By constructing the tool in the manner above described, it will beevident that when the levery 5 is swungto the right in Fig. l., thehooks 3 are caused to recede from each other, thereby allowing' them tobe hooked over the opposite edges of the rim R,'whereupon said lever isswung approximately to the position seen in said iigure, thus drawingone of the ends of the rim inwardly. To retain the rim in thiscontracted position. the chain 8 is now employed, clearly disclosed inFigs. l and il.

Although the inyention would ope-rate to great advanta if comprisingonly the features before described, it is :preferably equipped with anadditional pair of links 9, whose outer ends are provided with hooks l0,while their inner ends are pivote-d upon the bolt As shown in thedrawing, the two links 9 are shown as spaced .a suitable number ofdegrees from the linhs l and 2, it being; un derstood, however, thatsaid links 9 are free to be movedto any desired position.

From the' foregoing description, taken in connection with theaccompanying' drawing, it will be evident that al. hough a very' sim-vpletool has been provided for carrying ont the Object of the invention,the same will be very eiiicient in operation. and will possess a vnumberof advantageous Jleatures. Although the saine has been hereinbetoresuggested, it may' be well to direct attention to the fact that theyhooks 3 are formed by bending' the outer ends'ot the links 1 and 2outwardly in opposir directions and then inwardly, by whichconstruction, the hook one side of the rirn, while the other hook 3 willengage such Hang@ on the other side* thereof,v at a point spaceddiametrically from the irst-named hook. This is a rather salient featureof the invcmtion,y since the tool is readily held in position upon therim, and since the strain of contracting thev latterisinore nearlyequalized.

I claim:

l. `A tool comprising .a pair of links, having hooks at their outerends, a lever piv oted to the inner end of one of said links andpivotally connected to the inner end of the other link, and additionallinks carried bythe fulcruin oi the lever, and having hooks on' theirouter ends.

2. A tool, comprising a ypair ol' links,

having, hooks 0n theirfouter ends, a bell erank'lever pivoted at itsangle to the inner endof one link and having one of its arms pivoted tothe inner end of the other link, means in4 conjunction with onegoic theaforesaid links for locking the former in adjusted position. additionallinks said lever and carried by the fulcruin of the lever, andadditional hooks on the outer ends of said additional links.

3. A tool comprising a pair of links having hooks on their outer ends7 abell crank lever pivoted at its angle to the inner end `of one link and'having oneof its arms piv oted `to the inner end of the other link,means -in* conjunction with said lever and the second named link forlocking the former in adjusted position, and additional links pivoted attheir inner ends to said lever at its angle and having hooks on theirouter ends, one or the last named links ex tending radially on each sideof the first named link, the hook on the first named link facingoppositely from the hooks on the other links, as and for the purposedescribed.

In testimony set my hand in Witnesses.
